I tried the Dream World once, and it did not impress me in the least. If I wanted something to decorate, I'd want it in-game, like a secret base/villa/your room. The minigames are boring and there's not much you can do in just an hour a day. There's no reason none of the giveaways couldn't have been done through regular wi-fi. Nothing in the Dream World site prompted me to ever make a return visit.
